She's Coding (http://shescoding.org/) is a supportive, safe place for anyone identifying as woman or non-binary person in tech. We are a nonprofit organization with the main goal to help close the gender gap in tech, which we do via:
(1) An open-source website that educates women, allies and companies about the gender gap, developed in mentorship-based volunteer groups.
(2) A mentorship program, as well as an offline and online safe community for women in tech.
And (3), an effort to support women in their tech industry job searches via events, collaborations, and a yearly conference with career fair and workshops.
We currently run monthly 'regular' meetups with lots of networking and talks by our community members, extended duration codeathons, weekly technical interview preparation meetups, as well as mock interview events with partnering companies. All our meetups are open to women and non-binary folk.
